slimme-MACHINE.

To'aZZ whom 'itmay concern citizen of the United States, and a resident of Astoria, Queens county, and State of New York, have `invented certain new and useful Improvements. in Shaping-Machines, of -whicli the*following-is Aa description, reference being had toltlieaccompanyingdrawing, forming a -part thereof.

My 'invention-relates generally to shaping machines and relates more particularly to molding machines for shapingstones along curved Aor straight lines to form stone moldings for buildings and the like, although the shaping machine of my invention may be used for dressing curved or straight metal surfaces if desired. n

Objects of my invention are effectiveness and accu*racy -in operation, simplicity of construction, lcomparative inexpensiveness of p manufacture, facility of adJustment- .for curves of long or short radii or for straight' work, nonliability of derangement, and other .objects and advantages which will hereinafterl appear.

. My invention includes means for combinin such a Way that the resultant relative movements of Ithe 'tool and .the work will produce -the desired curves. A l

More particularly, my invention includes synchronizing ,connections lbetween a work ,carrier orwork supporting bed and a tool carrier, for controlling their relative movements so as-to produce the desired result.

In carrying outzmy invention. I have employed an actuating rod which, because of its :function in producing radius curves, 'I have called a radius link, a'nd shall` so designate this part hereinafter "in the description and claims., .Qne endv of the radius Ilink is adjustable along a lever, for producing curves .of different' radii.

Provision is made for producing either concave'orfconvex moldings, and in carryingy out my invention I have accomplishedl thisibymalriiig'connection-of the Ypart to be movedf'such as thetool carrier to the adjusting'leverat either the oneA side or the otheroffitsfulcrum, according as a con- My .invention 'also contains .other advantageous features of construction and combi- -.Specication of Letterslatenc.'

In the machine embodying my -invention illustrated in the drawings the invention is shown as applied to and combined with the machine which in other respects than modified lby my invention `is constructed as a usual planer or straight molding machine.

The work yis supportedv on a horizontal work carrier or work-supporting'bedl above .which is hung lthe tool 2, shown as a'rotary tool. The bed l is supported by a base 3 provided, as appears in thedrawin s, with V-shaped guides or ways into .which t guide rails formed on the bed l'. l provided .with usual longitudinal T-shaped slots lor'grooves for usein clamping the workin place. The vwork-supporting bed 1 l is adapted to 'be reciprocated jor fed back and forth 'longitudinally on the base 'f3 by` usualor any siiitablefeed mechanism, shown in .the drawingsv as including a feed rack 4 on lthe under sideof the bed'l engagedby a feed gear '5. l l' A feed shaft 7 .extends 'transversely' of the machineand is connected w'iththe feed gear The lbed 1 is 5 through a'train of reducinggearing shown as a Ypinion 12.011 the end' of thei'feed shaft at the right engaging a gear'1'1 on an `intermediate shaft whichis provided -with a -pinion 10 directly meshing with the feed Lgear 5. 'A feed actuating bevel gearlB,

` belt 21' with a main feed shaft 22 journaled on the upper part of a main frame 23-and adaptedto be driven from any source of power by a belt pulley 24.

The rotary tool is vfixed on a horizontal sleeve 25 journaled in bearings or journal boxes on a tool carriage 26 provided, as shown, with gibs engaging guide-ways on a cross-frame 27, to permit lateral adjustment of the tool carriage 26 and tool 2 carried thereby. The journal boxes 26a and 26b on the tool ycarriage 26 for the .tool-carrying sleeve 25 are shown as suitably spaced, the journal boX 26a being movable along the rod 65, its inward movement, however,- being limited by the spacing rods 62. The sleeve 25 is shown as screw-threaded, the rotary tool 2 being clamped in position thereon by a nut 28and intervening spacing or filling washers 29, this arrangement permitting ro-l tary tools of different axiallength to be mounted on the tool-carrying sleeve 25, and

.also in case ofl a comparatively thin tool,'

such as the tool 2 shown in the drawings, permits lateral adjustment ofthe tool along the tool-carrying sleeve 25, relatively to thecarriage 26. l l

'The rotary tool 2 is adapted to be driven by a tool-driving shaft 30 journaled on the cross-frame 27 and splined to the tool-carrying sleeve 25 so as to impart rotation to this sleeve and .to the tool while permitting lateral adjustment ofthe tool 2 by movement of the tool carriage 26 along the guideways on the cross-frame 27. n The tool-driving shaft 30 may be driven from any source of power by means of a belt pulley 31 on the tool-drivingfshaft 30. s

To permitthe tool, such as 2, to operate on work of different thicknesses o r` at different heights, and also to provvide for feedthe tool 2 downto the work 70, the cross- Vframe 27,' which supports the carriage 26 and tool 2,A is vertically adjustable on the main frame 23 by means of lifting screws 32 screw-threaded through the end portions of th cross-frame and journaled at "their upper ends in screw-supporting blocks 33 and geared to a screw-actuating shaft 34 .also j ournal'ed in bearings on theblocks 33.A The screw-actuating shaft 34 may be manually rotated to raise or lower the tool 2 by means of a stub-shaft 35, to which the wrench or crank may be applied, shown as connected bysprockets and a sprocket chain 36 to the screw-actuating shaft 34, and journaled in a bearing 'at the lower end of a vertical supporting bar 37 depending from one of the bearings ofthe-shaft 34 and guided in a bracket 38 on an end vof the cross-frame 27.

The construction of the machine as so far described is substantially that of an ordinary planer or surfacing machine, but l"had to be `first described in order to' properly understand the application thereto and combination therewith ofthe parts .of the ma chine introduced i by my invention and which will now be described. In carrying out my invention, as applied to the planer type of machine illustrated in the drawings, the .supporting blocks 33 in which .the lifting screws 32 are journaled and supported, are so connected to the work supporting bedlthat vertical movements will be imparted to the cross-frame 27 through the screws 32, and consequently to the tool carriage 26 and tool 2,4in synchronism with the longitudinal movements of4 the work-supporting bed 1 and at a relative varying ratio andl offa relative extent to produce the desired radial curve in vertical planes on the upper surface of the work.

'A connecting and supporting bar or shaft.

tive of the vertical adjustment thereof provided by the lifting screws 32.

A sleeve 43 is loosely mounted on the mid dle portion of the rock shaft 42. The

rocker arm 40 and the adjacent end of the sleeve 43 are shown as provided respectively with oval flanges 40a and 43a adapted to -be rigidly connected together by bolts passing through both flanges, or these flanges may be left unconnected by the removal of the bolts, the latter being the condition illustrated in Figs. l, 2 and 3." The sleeve 43 is also provided with a rockerarm 43b which normally extends horizontally rearwardly therefrom. A connecting 'rod 44 pivotally connects the arm 43b of the sleeve 43 with a cross-head 45 having a guide stem 46 guided for vertical movement in brackets projecting from the main frame 23, as shown. second and two-part connecting rod 47 pivallyconnects'the.cross-head 45 with the supporting bar 39. The two parts 47a and 47b (F ig. 4.) of the vconnecting rod 47 may be left disconnected from one another, or they I mdf With the flanges4.C

oval coupling flanges 47C and bolts holding the fianges together, the latter being the condition illustrated in the drawings.

dition shown.y in. the. dra-Wings, Will. alternately raise andlower or vertically recipror Cate. thetool 2e The. mechanica-1. connection. is traceable from the, Sleeve 43 'through the rocker arm 431?, connecting rod 44,;'crosshead 45 andthecounected two-partconnecting rod 47 to thesupporting bar 39, which may, have' free Substantially vertical movemQXltby reason of` thej freedom of the rocker arms 40 and 4,1 and the rock shaft 42 by which the ,supporting bar 39 willbe steadiedi and guided- It can furthert be readily understood that ifl the two. partsof the twopart connecting rod 47 be disconnected and the flanges 40n of the rocker arm 40 and 43a of the Sleeve 43 be coupled together, that rocking, 'or oscillation of' the sleeve 481will when communicate vertical reciprocating movements to the tool 2I through the rock` shaft 42 and rocker arms'40 and 41 keyed thereto and vconnected directly vto the supporting bar 39, the connecting rodf44-and the cross- `head 45 then movingidly, but it should be noted however that in this instance the vertical movements of the supporting bar 39 will be in opposite directions, as compared tothe direction of oscillation ofthe sleeve 43, to what they were in the first instance actuating connection was made through the connecting rod 44 and crosshead 45, as'illustrated in the drawings.

A long normally horizontal actuating lever 48 is secured to the sleeve 48 and projects rearwardly over the work-supporting bed 1 and base 3, being shown as substantially coterminous with the latter. A lever-actuating rod or radius link 4 9 pivotally connects the lever 48 with the work-'supporting'bedL The radius link 49 is shown as made of two parts joined'by a turnbuckle 49a, to provide for longitudinal adjustment of the radius link. The upper'end of the radius link 49 is provided with a yoke 49c partly embracing the lever 48 and pivoted to a pivot block 50'adjustable longitudinally of the lever 48 by means of an adjusting screw 51 journaled in the lever, and having, as shown, a

y squared projecting end portion, for engagement of a wrench or crank handle. The lever 48 is provided with a scale 48a, as shown in-Fig. 1, to indicate the point of adjustment of the upper end of the radius link along the lever. The lower end of the radius link 49 is provided'with a similar yoke 49b pivoted to a fulcrum block 52 which is conveniently securedZV to the work-supporting vbed 1 for adjustment longitudinally thereof by means of a` T-bolt entering one of the usual longitudinally T-shaped work clamping grooves therein. f

Inorder to reduce thefstrain on the lever 48, I have provided a counterbalancing arm' fixed by a hub 75, as the rock shaft' 42'and on which a weight76jis adjustably mounted andheld. in place by a screw 77. y It can. now be understood that the reciprocatory'movements of the work-supporting bed 1 will be translated into vertical movements of the tool 2, through the angular thrust, or pull, as the case may be, ofthe radius link 49. The arc that would be described by one end of the radius link were it swung about a stationary pivot at its other end willl be described on the work in magnified or reduced degree, according to the upper end of the radius link describes substantially the perpendicular. "The work, carried by the bed 1, describes the same l chord asthe lower end of the radius link 49 and the tool describes a reduced or a magnified perpendicular of j the upper end of the radius link 49. In some machines, to which this invention is applicable, the main frame, such as 23, cars ries the tool, such as 2, back and forth over a stationary bed. In such a machine the lower end of the radius rod 49 would remain stationary while the upper end would move in the same arc which, in adjusted degree, would be impressed on the tool, the work being stationary. If, in the machine illustrated in the drawings, the manner of operating the machine is such, as would usually be the case, that the lowerend of the radius linkV is carried past the center line, that is to say, past the perpendicularv position of therathat described by dius link, the tool 2 will 'receive two vertical movements in opposite directions foreach one-way movement of the bed 1. It is to be I movement which, when combined with the rectilinear horizontal movement of the bed 1, gives the desired radial curve to the work. This sine curve movement of thetool carrier of course is not continuous but is incomplete and is interrupted and reversed atl each reversal of movementof the bed l.

r1`he tool`2 will either traverse a convex or concave surface on the work as desired, or the machine may be adjusted for straight line Work. Inthe adjustment of the machine illustrated in the drawings, the sleeve` 43, to which the actuating lever 48 is se- Ts'ured, is disconnected from the rock shaft 42 and is connected tothe supporting bar lthrough the cross-head and connecting rods 44 and 47, as has' been hereinbefore noted, 'so that the tool 2 will be moved in the same direction as the lever 48 and upper end of the radius link 49, and `will therefore, act upon a convex surface of the work, for example, for producing an outside molding, such as indicated by the work 70 Ashown on the bed 1 in Fig. 1. It is readily seen that, in another adjustment of the machine, with the lever 48 directly connected to the rock shaft 42 and with theconnection from the cross-head 45 to the supporting bar 39 discontinued, vthen the tool 2 would be moved in an opposite'direction to vthe lever 48 and. upper end of the radius link 49 andwould act upon a concave surface of the work,for producing an inside molding, for example.

To adjust the machine for straight linework, for example, for `making straight moldings, the sleeve 43 should be fixed on the rock shaft 42, by bolting together the flanges 40EL of the rocker arml 40 and 43a of the sleeve 43; also bolt together-the coupling flanges 47 c of the two-part connecting `rod 47, and remove the radius link49. The double connection thus eiected will hold 28, vso that the` rotary tool 2 will 'remain bodily stationary while the workvis moved 'beneath-it by the work-supporting bed 1:

The operation of the machine is rendered i continuousby means of usual trip dogs 53 longitudinally -adjustable along the edge of the bed l and adapted to engage and actuate a lever of the reversing clutch l5, hereinf before described. The lever mayofcourse` be i'nanually actuatedto stop the feed or to reverseit at any point desired. i

1n the drawings I have shown an abrasive tool of thevrotary type. It is obvious that tools of different character and form could beA employed. In'Fig. 7, I have shown the machine equipped with an attachinent forF turning out balusters and the like. The rough piece of work 71 is mounted in. a lathe-like structure 6l of the usual form and the work rotated. vIt is fed. up against' the tool 2 in the usual manner.

` It is obvious that various .modifications i,

may be made in the construction shown in lthe drawings and above particularly describedwithin the principle and scope of my invention.
